Job title:

Automated control and acquisition system for ultrasonic scanning measurements

Location:

Clamart, France

Scope of the internship:

The internship is centered on building a laboratory setup with an automatic control and data acquisition system for the purpose of ultrasonic scanning measurements.  The objective is to create a computer-controlled system to manipulate ultrasonic sensors in three-dimensional (3D) space (xyz-stage) in front of various underwater targets in a small tank and to design and build an associated acquisition system with sensor firing, waveform acquisition and data processing.  The 3D scanned ultrasonic measurements are then used in experiments to determine acoustic beam characteristics (such as beam width, beam intensity and measurement resolution) of sensors. Python is used to develop the control software. MATLAB or Python are used for data processing. Ultrasound pulse-echo techniques are employed in prototype tools currently under development for subterranean applications. The objective of the tool measurement is the characterization of borehole dimensions and geological features during drilling. The intern acquires an in-depth understanding ultrasonics as used in non-destructive testing and structural health monitoring by creating a fully automatic measurement and acquisition system. Geophysical and geo-mechanical topics are introduced. Concepts of wave propagation, time-resolved measurements are explored to advance the understanding of the measurements.

Responsibilities:

 

  • The intern uses the available components of 3D stage, ultrasonic pulser box, acquisition system (Picoscope), water tank, piezo-electric transducers and laptop to create the computer-controlled measurement control and acquisition system.
  • The following responsibilities are planned:
  • Hands-on assembly in the laboratory of the setup components
  • Programming the measurement control and acquisition system
  • Testing of the system in the water tank with piezo-electric transducers
  • Data analysis of ultrasonic pulse-echo measurements by the laboratory experiments on sample targets.

She/he develops or adapts data processing algorithms to extract key parameters of the acoustic echo waveforms.  The intern furthermore generates images of the sensor beam profiles, evaluates measurement sensitivity, resolution and develops processing improvements.  Deliverables: Internal presentations of results, Reports on experiments and data analysis.

Skills required:

  • Master of Engineering school
  • Autonomous and able to work in a team
  • Appreciate the culture of product delivering, curious to learn and ambitious.
